High levels of silt content in the sand can reduce its strength, cohesion, and permeability, making it less suitable for use in certain types of construction projects. ... Fineness Modulus of Sand Test ...
The fineness modulus of MS should be controlled between 3.0 and 3.4. If the fineness modulus is more than 3.5, there are too many coarse particles and too few particles smaller than 300 μm, so the grading is unreasonable, which induces worse workability of concrete. If the fineness modulus is less than 3.0, there is too much fine …
